This invention relates to an improved hairwaving apparatus adapted to be used in the operations of curling or waving hair by theapplication of heat, the general character 'of hair-waving "apparatus adapted for facili-v tating rapid operations being disclosed-in. Letters Patent granted to me' February 18,- '1930, No. 1,747,787; the present invention 7 having reference more particularly to means waving human hair are performed for adjustably supporting and controlling electric heaters whereby the operations of An object of the invention is to provide an improved stand of electric heaters and controlling apparatusfor halr-waving operations, whichshall be of simple and efiicient construction and not be costly to manufac ture.

Another object is .to provideimproved means for adjustably supporting electric heaters necessary in the operations of hamwavin and hair curlin to advanta e withb t) C 7 out depending upon circuit wires for supporting the heaters, which apparatus shall be so constructed as to permit rapid assembly of parts and also replacement of parts that might become necessary as a consequence of accident, long use and wear of operating arts. p A further object is to provide new and simple means whereby to cause frictional resistanceon controlling cords that may be used to adjustably support!v the electric heaters, without entailing the use of counterweights for the heaters and necessary means for guiding the counterweights, an aim of the present invention being to provide noiseless cord-controlling means in adome of small bottom area that shall offer the least obstruction to convenient manipulation of the heaters.

A. still further object is to provide an improved unit of adjusting devices which shall i be of such. construction as to be adapted to noiselessly operate in an-improved manner, and which shall not be costly to manufacture and shall be adapted to be durable and economical in use.

lNVith the above-mentioned and other objects in view, the invention consists in a novel unitary controlling apparatus and an imnumber of the devices arranged therein. 7

of'the dome, minus'the cover part of the dome,the arrangement of the controlling devices or cord tensioners being shown in horizontal section; Fig. 5 is an elevation of a novel holder or controlling device base and a k Similar reference characters in the different figures of the drawings indicate corresponding elements or features of construction herein referred to in detail. r r e As preferably constructed the new hairwaving apparatus comprises a portablebase 1 and a standard comprising a main part 2 secured thereto and having a curved arm- 3 that reaches laterally a suitable distance to conveniently support the dome of the apparatus. The dome is composed of spun or die-pressed sheet metal preferably composed of two principal-parts to constitute a hollowhousing, there being a main. or lower partthat is substantally urn-shaped, and a semi-globu lar cover or top part. The main part has a small circular bottom 4 and ornamentally flared side wall 5 of which a portion is only slightly inclined to constitute a bench porthe cover having a depressed portion 10 as preferably constructed, and the upper and lower parts of the housing are detachably secured together by means of a suitable bolt or screws 11.

A hollow or cup-shape holder is provided which has a bottom 12 and cylindrical side wall 13 having a flared upper portion 14, the cup being centrally arranged upon the housing bottom 4. A suitable number of elastic controlling devices or tensioners are provided, one for each electric heater required, two of the tensioners being shown as suflicient to an understanding of the invention and comprising base portions 15 and 15 and main operative portions 16 and 16 respectively, the base portions being arranged in the cup against the wall 13 thereof and finedly secured therein by means of a cup-shaped core 17 forced into place and preferably having a. bottom 18 supported on the bottom 12. A center rod 19 is provided which is inserted through the depressed portion 10 oi the cover portion of the bolt being screw-threaded and having a nut 20 thereon that engages the bottom 18 and also a nut 21 engaging the under side of the bottom 4. The upper portion of the rod also is screw-threaded and extends through the depressed portion 10 of the cover part and is screwed into and through the terminal portion of the standard portion 3. A nut 22 is arranged beneath the depressed portion 10 and a nut 23 is arranged on the rod upon the bottom of the depressed portion to secure the principal parts of the llOusing together in a firm manner, and the rod preferably is provided with a lock nut 24 engaging the upper face of the standard arm. The housing is preferably secured against rotation under the arm by means of a bolt 25 insorted through the cover 9 and screwed through the arm portion 3 and provided on its end with a lock nut 26.

The bench portion 6 of the housing has a suitable number of apertures 27, and 27 to accommodate the required number of electric receptacles 28,28, the receptacles being conventionally connected with circuit wires 29 adapted to have plugs 30, 30 detaehably connected thereto and to which electric cables 31, 31 are connected to conduct electric energy to suitable curler heaters, each heater preferably being of the clamping type comprising arms 32 and 33 pivotally connected together and having curved heater plates 34 and 35 thereon respectively that are adapted to be applied to hair coils in a customary manner.

A supporting cord 36 is provided for each electric heater and is suitably attached there to, one end of the cord being connected to the lever 32, the cords extending through suitable guide holes 37, 87 and into the housing, each hole having a guide bushing 88 therein ough which the cord loosely extends to an elastic tensioner. Each cord has a stop collar 39 thereon that is counter-bored in its outer portion to receive a knot 40 with which the cord is provided to prevent the cord from slipping through the collar when the latter is stopped against the bushing. The inner side of the housing wall is provided with a guide eye having a shank 41 which is conveniently fastened to the wall by a bushing suitably upset to constitute a hollow rivet. Preferably the shank has two guide eyes 42 and 43 integral therewith that are arranged slightly higher than the inner end of the bushing. Each tensioning controller is provided on its outer side with guide eyes 44 and 45 integral with a shank 46 set into a perforation 47 in the controller adjacent to its upper end and secured in place by bending the shank over the top of the plate. The

cord may be passed through the eye 44 and back to the eye 42 and secured thereto as in dicated in Fig. 1 when the eye 44 affords sutlicient frictional resistance to support the type of heater that may be supplied. Preferably the cord is passed from the guide bushing 38 to and through the eye 45, thence to and through the eye 43, thence the eye 44 and thence to the eye 42 and having a knot 48 or other means securing the end of the cord to the eye. The required electric circuit for conducting current into the housing is afforded by means of a cable 49 and conveniently distributing the electric current to the various plug receptacles, as customary.

Preferably each elastic controller in practice is composed of a flat strip of tempered steel similar in character to clock spring material. Each shank or base portion 15 is straight while the operative main portion 16 slightly curved so as to extend inwardly or towards the rod 19 when primarily set in place in the holding cup and is subsequently sprung outward by the supporting cord when threaded through the eyes, so that the controller is then under tension and puts the cord under tension.

In practical use strands of hair are suitab y prepared for treatment, the subject to be treated being seated under the dome or housing and the heaters drawn down and clamped to the prepared hair strand to be subjected to the electric heat in a well-known process. As the heater is drawn down to convenient position for use the supporting cord is drawn out and pulls the controller outward or over towards the wall of the housing, the frictional re i tance caused by the guide eyes affording sufficient tension to enable the cord to support the weight of the heater in the position in which it may be placed, the controlling tensioner maintaining the cord in taut condition. As the opcr ator lifts the heater after use all slack in the supporting cord is taken up by the elastic controller so that with the aid of the fric tional resistance of the cord in the eyes the through the wall of the housing.
